A Preliminary Assessment on the Plankton Diversity of Serlui 'B' Dam in Mizoram, Northeast India Sci Vis 17 (4), 238—246 (2017) Available at www.sciencevision.org OPEN ACCESS Research Article A preliminary assessment on the plankton diversity of Serlui ‘B’ dam in Mizoram, northeast India Esther Lalhmingliani,* Freddy Lalrinpuia Department of Zoology, Mizoram University, Aizawl 796004, India Planktonic sampling was carried out at Serlui ‘B’ dam, Mizoram, northeast India from July Received 18 November 2017 Accepted 30 November 2017 2016 to April 2017. The present study reported the occurrence of 6 groups of phytoplankton belonging to 27 genera and 16 orders and 4 groups of zooplanktons belonging to 12 genera *For correspondence : 7 orders. The phytoplankton group consisted of Cyanophyceae, Bacillariophyceae, Ulvophy- [email protected] ceae, Zygnematophyceae, Chlorophyceae and Xanthophyceae. Cyanophyceae were the pre- dominant component of phytoplankton in Serlui ‘B’ dam during all seasons in terms of nu- merical abundance and account for 64% of the total phytoplankton. The zooplankton groups consisted of Maxillopoda, Tubulinea, Eurotatoria and Branchiopoda. Of these, the class Maxil- lopoda was the predominant component of zooplankton in Serlui ‘B’ dam during all season in terms of numerical abundance and account for 73% of the total zooplankton encountered from the study site. This study provides preliminary report of planktons of Serlui ‘B’ dam.

    INTERNAL QUALITY ASSURANCE CELL (IQAC) GOVERNMENT J. THANKIMA COLLEGE 2020-2021 ACADEMIC SESSION BEST PRACTICE 1 UTILIZATION OF ICT AND ONLINE CLASSES 1. Title of the Practice: Utilization of ICT and Online Classes ▪ The sudden outbreak of Corona Virus worldwide with the inclusion of Mizoram has resulted in the suspension of the Conventional face to face Classroom teaching, with effect from March, 2020. However, classes were continued through online mode for the benefit of the student- learners. Zoom classes and power point presentations with audio were carried out as much as possible. Classes were also conducted through WhatsApp messengers, which also act as an instrument for announcement and monitoring the students on a daily basis. 2. Objectives of the practice: ▪ Due to the current global health emergency, the daily routine and learning habits have probably been disrupted enormously. The inability to continue with the conventional mode of teaching after March, 2020, faculties are compelled to continue with online mode of teaching. The Institution and faculties aim at restructuring the system of teaching-learning method. ▪ Hence, online classes have been integrated into existing academic structure and process. Time Table was sorted by AEC for the convenience of conducting online classes, and classes were conducted accordingly in these unprecedented times so as to achieve and accomplish certain pre-defined, pre- existing learning goals. The objective is student-centric and in tandem with the college teaching norms: ▪ Online classes for the overall benefit of the students- i.e., making use of online tools for effective learning and effective time management during the pandemic.

Bhattacharjee of the Indian Administrative Service Director of Census Operations, Mizoram .: ..... ", "'I. ., '.. ... "a CHERAW One ofthe most unique and interesting dance called "Cheraw" is sometimes known as 'Bamboo Dance' just because ofusing bamboos during the dancing. The dancer performs the dance by an alternate stepping in and out from between and across a pair ofhorizontal bamboos, which are held against the ground by boys. The bamboos open and close in rhythmic beats. The horizontal bamboos are supported by two bases one at each end. The bamboos when clapped, producing a sharp clapping sound which give the rhythm and timing to the dance. The dancers steps in and out to the beat ofthe bamboos and maintain the dance with confidence and grace. There are many variations in pattern and steps in Cheraw, imitation ofthe movement ofbirds, the swaying ofthe tree and so on. The origin of Cheraw is not known for sure. Probably the forefather of the "Mizos brought it from far East. Although Cheraw is performed now on any occasion, originally it was performed, so says the legend, with a specific purpose to pave a safe and victorious passage for a child (on leaving this mortal world) to the abode ofthe dead 'Piaral' (paradise). Cheraw is therefore, a dance of sanctification and redemption performed with calculated precision and elegance.

    Advances in Engineering Research, volume 178 Mizoram Science Congress 2018 (MSC 2018) Assessment of plankton diversity of Tlawng River at Reiek Kai in Mizoram, Northeast India Esther Lalhmingliani*, Lalhminghlua Department of Zoology, Mizoram University, Tanhril 796004, Mizoram, India Corresponding author: [email protected] Plankton diversity of Tlawng River at Reiek kai in Mizoram, Northeast India, was investigated during 2017 to 2018. A total of 16 genera of phytoplankton belonging to 10 orders and 5 groups, and 7 genera of zooplanktons belonging to 7 orders and 5 groups were encountered. The phytoplankton group consisted of Chlorophyceae, Zygnematophyceae, Cyanophyceae, Bacillariophyceae and Ulvophyceae. Bacillariophyceae were the predominant component of phytoplankton in Tlawng River during all seasons in terms of numerical abundance and account for 60% of the total phytoplankton. Majority of the phytoplankton were encountered during the summer season. The zooplankton group consisted of Copepoda, Tubulinea, Branchiopoda, Rotifera and Nematoda. Of these, the class Copepoda were found to be the most dominant constituting 59% of the total zooplankton population encountered during the sampling period. The least dominant group among the zooplankton were Tubulinea constituting only 4% of the total zooplankton population. Unlike the phytoplankton where summer season harboured maximum number of individuals, the zooplanktons were encountered mostly during the winter season.
